Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0012711 filed on Jan. 31, 2019 in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

BACKGROUND

1. Field

The disclosure relates to a cleaner, and more particularly, to a cleaner including a button for separating a dust separator from a main body and separating a dust container from the dust separator.

2. Description of Related Art

In general, a cleaner is a home appliance that sucks air containing foreign substances such as dust using a suction force generated by a motor installed inside a main body, separates the foreign substances contained in the air by a dust separator, and then discharges the air from which the foreign substances have been removed to the outside.
The cleaner includes a main body in which the motor is installed, and a dust collector detachably coupled to the main body. The dust collector includes a dust separator, and a dust container detachably coupled to the dust separator.
In general, the cleaner includes a button for separating the dust separator from the main body and a button for separating the dust container from the dust separator. In this case, a user needs to operate the buttons according to situations by learning the functions of the buttons, which deteriorates ease of use. In addition, because spaces for installing the buttons are required, utilization of space may be lowered.
Also, in a process of separating the dust container from the main body, the dust container may fall to the floor due to its own weight contrary to a user's intention. Furthermore, when the dust container falls to the floor, dust inside the dust container may pour to the outside, and in this case, cleaning needs to be again performed.

FIG. 1 illustrates a perspective view of a cleaner according to an embodiment of the disclosure, FIG. 2 illustrates some components of the cleaner according to an embodiment of the disclosure, and FIG. 3 illustrates some components of the cleaner shown in FIG. 2 at another angle.
A cleaner 1 may include a main body 10, dust collectors 40 and 50 detachably coupled to the main body 10, and a suction device 30 detachably coupled to the main body 10.
The main body 10 may include a motor configured to generate a suction force. The motor may be positioned inside a motor housing 60.
The dust collectors 40 and 50 may be positioned upstream of the motor, and may separate and store dust or foreign substances contained in air entering a suction port 51 through the suction device 30. The dust collectors 40 and 50 may include a dust separator 40 configured to separate dust or foreign substances contained in air entered through the suction device 30, and a dust container 50 configured to store the dust or foreign substances separated by the dust separator 40.
As shown in FIGS. 1 to 3, the dust collectors 40 and 50 may be detachably coupled to the main body 10.
The dust container 50 may include the suction port 51 which air sucked by the suction device 30 enters. The dust container 50 may include a protrusion housing 52, and a sliding protrusion 53 slidingly coupled to or inserted into the main body 10. A detailed description about the protrusion housing 52 and the sliding protrusion 53 will be given later.
The main body 10 may include a handle 11 to allow a user to grip and control the cleaner 1. The user may grip the handle 11 and move the cleaner 1 in front and rear directions.
The main body 10 may include a controller 12. The user may operate a power button or the like provided on the controller 12 to turn on/off the cleaner 1 or adjust a suction force.
The main body 10 may include a battery 13. The battery 13 may be detachably coupled to the main body 10. Accordingly, after the battery 13 is exhausted, the battery 13 may be replaced by another charged battery to increase an operating time of the cleaner 1. Alternatively, the battery 13 may be integrated into the main body 10.
The main body 10 may include a filter housing 15. The filter housing 15 may have a substantially donut shape to accommodate a filter therein. There is no restriction on a type of the filter, however, for example, a HEPA filter may be positioned in the filter housing 15. The filter may filter ultrafine particles and the like not filtered by the dust separator 40. The filter housing 15 may include a plurality of holes 15 a to allow air passed through the filter to be discharged to an outside of the cleaner 1.
The main body 10 may include a sliding rail 20, a sliding groove 21, and a guide portion 22 configured to couple the dust collectors 40 and 50 to the main body 10. A detailed description thereof will be given later.
The suction device 30 may include a suction head 31 and extension pipes 32 and 33.
The suction head 31 may come into contact with a surface to be cleaned to suck foreign substances such as dust existing on the surface to be cleaned.
The extension pipes 32 and 33 may connect the suction head 31 to the main body 10. One end of the extension pipes 32 and 33 may be pivotally connected to the suction head 31. Accordingly, the suction head 31 may perform a joint motion with respect to the extension pipes 32 and 33.
The extension pipes 32 and 33 may include the first extension pipe 32, the second extension pipe 33, and a length adjusting portion 34. A length by which the second extension pipe 33 is exposed to the outside may be adjusted through the length adjusting portion 34. By adjusting a total length of the extension pipes 32 and 33 through the length adjusting portion 34, a user may select a length of the extension pipes 32 and 33 according to his/her height. Conventionally, a long or short extension pipe has been used according to a user's height. However, in the disclosure, a user may adjust the length of the extension pipes 32 and 33 to his/her desired length. Therefore, ease of use of the cleaner 1 may be improved.
The main body 10 may include a suction device connecting portion 14. The suction device connecting portion 14 may separate the suction device 30 from the main body 10 or couple the suction device 30 to the main body 10. The cleaner 1 may include various types of suction devices, and each suction device may be detachably coupled to the main body 10 through the suction device connecting portion 14.
The dust separator 40 may include a button 100. The button 100 may separate the dust collectors 40 and 50 from the main body 10 or couple the dust collectors 40 and 50 to the main body 10. The button 100 may also separate the dust container 50 from the dust separator 40 or couple the dust container 50 to the dust separator 40 when the dust collectors 40 and 50 are separated from the main body 10. According to an embodiment of the disclosure, the button 100 may be used to separate the dust collectors 40 and 50 from the main body 10 and the dust container 50 from the dust separator 40. That is, a user may operate the button 100 to separate the dust collectors 40 and 50 from the main body 10 and the dust container 50 from the dust separator 40. Therefore, ease of use of the cleaner 1 may be improved.
FIGS. 4 and 5 are cross-sectional views taken along line A-A′ of FIG. 1, illustrating an operation of the button when the dust collector is separated from the main body.
Hereinafter, the operation of the button 100 will be described in detail with reference to FIGS. 4 and 5. Hereinafter, a first locking portion and a second locking portion may indicate a button coupling portion 70 and a button hole 54, respectively.
Referring to FIGS. 4 and 5, the button 100 may include a first protrusion 101, a second protrusion 102, and a third protrusion 103. The button 100 may be rotatable on a rotation shaft 104. The button 100 may also include a hook groove 105 formed adjacent to the first protrusion 101.
The filter housing 15 may include a button coupling portion 70 (see FIG. 3). The button coupling portion 70 may include a stopper 71 protruding from the filter housing 15 toward the button 100, a hook 72 extending downward from the stopper 71, and a protrusion groove 73 formed between the filter housing 15, the stopper 71 and the hook 72.
The first protrusion 101 may fix or release the dust separator 40 to or from the main body 10. The first protrusion 101 may be inserted into the protrusion groove 73 or taken out of the protrusion groove 73. The first protrusion 101 may be inserted into the protrusion groove 73 to fix the dust separator 40 to the main body 10. The first protrusion 101 may be taken out of the protrusion groove 73 to release the dust separator 40 from the main body 10.
The second protrusion 102 may come into contact with the stopper 71 to restrict a movement range of the button 100. The button 100 may rotate in a first direction. When the button 100 rotates in the first direction, the second protrusion 102 may come into contact with the stopper 71. When the second protrusion 102 is in contact with the stopper 71, the button 100 may be restricted from rotating in the first direction. Thereby, when the dust collectors 40 and 50 are separated from the main body 10, the dust container 50 may be prevented from being separated from the dust separator 40. As will be described later, the dust container 50 may be separated from the dust separator 40 when the dust collectors 40 and 50 are separated from the main body 10.
The third protrusion 103 may be inserted into the button hole 54 provided on the dust container 50. When the third protrusion 103 is inserted into the button hole 54, the dust container 50 may be prevented from being separated from the dust separator 40. As shown in FIG. 5, when the second protrusion 102 comes in contact with the stopper 71, the button 100 may be restricted from rotating. Because the third protrusion 103 is maintained in a state of being inserted into the button hole 54 when the second protrusion 102 is in contact with the stopper 71, the dust container 50 may be not separated from the dust separator 40.
The dust separator 40 may further include an elastic member 110. The elastic member 110 may provide an elastic force to the button 100. The elastic member 110 may provide an elastic force when the button 100 rotates in the first direction so that the button 100 rotates in a second direction that is opposite to the first direction to return to its original position. Thereby, the dust collectors 40 and 50 may be prevented from being separated from the main body 10 due to the first protrusion 101 taken out of the protrusion groove 73 contrary to a user's intention.
FIG. 6 illustrates a side cross-sectional view of the dust collector in the cleaner according to an embodiment of the disclosure, and FIG. 7 illustrates a process of separating the dust container from the dust separator in the cleaner according to an embodiment of the disclosure.
Referring to FIGS. 6 and 7, the dust container 50 may be separated from the dust separator 40. Unlike FIGS. 1 to 4, when the dust collectors 40 and 50 are separated from the main body 10, the dust container 50 may be separated from the dust separator 40.
When the dust container 50 is coupled to the dust separator 40 simply by coupling of the third protrusion 103 and the button hole 54, an external force applied to the dust container 50 may separate the dust container 50 from the dust separator 40. To prevent this, the dust container 50 may include a fixing protrusion 55, and the dust separator 40 may include a fixing portion 42. As shown in FIG. 6, the fixing protrusion 55 may be inserted into the fixing portion 42 and the third protrusion 103 may be inserted into the button hole 54, so that the dust container 50 may be stably coupled to the dust separator 40.
The dust container 50 may include the suction port 51 provided on one surface of the dust container 50. The dust separator 40 may include a cyclone portion 41. A plurality of the cyclone portions 41 may be provided.
Air sucked through the suction head 31 may enter the suction port 51 through the extension pipes 32 and 33. When the air entered the suction port 51 passes through the cyclone portion 41, dust contained in the air may be removed, and the air from which dust has been removed may pass through the filter to be discharged to the outside of the main body 10 through the holes 15 a of the filter housing 15.
FIGS. 8 and 9 are enlarged views of a portion B of FIG. 6, illustrating an operation of the button when the dust container is separated from the dust separator.
Hereinafter, the operation of the button will be described in detail with reference to FIGS. 8 and 9.
As shown in FIG. 8, even when the dust collectors 40 and 50 are separated from the main body 10, the button 100 may be positioned at a predetermined position by an elastic force of the elastic member 110. The predetermined position is referred to as a first position. The first position is an original position of the button 100 before the button 100 rotates in the first direction.
Referring to FIG. 5, when the dust collectors 40 and 50 are separated from the main body 10, a rotation range of the button 100 may be restricted by the stopper 71. As described above, because the third protrusion 103 is not taken out of the button hole 54 even when the button 100 rotates in the first direction within the restricted rotation range, the dust container 50 may be prevented from being separated from the dust separator 40. A position of the second protrusion 102 at which the second protrusion 102 is in contact with the stopper 71 is referred to as a second position.
Referring to FIG. 9, when the dust collectors 40 and 50 are separated from the main body 10, a rotation range of the button 100 may be not restricted by the stopper 71. Thus, the button 100 may rotate in the first direction from the second position. When the button 100 rotates in the first direction from the second position, the third protrusion 103 may be taken out of the button hole 54. When the third protrusion 103 is taken out of the button hole 54, as shown in FIG. 7, the dust container 50 may be separated from the dust separator 40. As described above, the button 100 may be used not only to separate the dust collectors 40 and 50 from the main body 10 but also to separate the dust container 50 from the dust separator 40. Therefore, two separate operations may be performed by using the button 100, thereby improving ease of use. In addition, utilization of space may be improved compared to a case of providing buttons separately. According to the disclosure, a larger dust storage space may be secured compared to another dust container of the same size. In addition, the dust container 50 may have a smaller size than another dust container of the same dust storage space.
FIGS. 10 to 12 illustrate various methods of coupling the dust collector to the main body in the cleaner according to an embodiment of the disclosure.
According to the disclosure, the dust collectors 40 and 50 may be coupled to the main body 10 by various methods.
As shown in FIG. 10, by aligning a center of the dust collectors 40 and 50 with a center of the filter housing 15 and then causing the dust collectors 40 and 50 to slide in a lateral direction, the dust collectors 40 and 50 may be coupled to the main body 10. The lateral direction may indicate a direction in which the sliding rail 20 extends. When the dust collectors 40 and 50 are coupled to the main body 10 by the method, the sliding protrusion 53 may be inserted into the sliding groove 21 by sliding without being elastically deformed. A description thereof will be given later.
As shown in FIG. 11, by moving the dust collectors 40 and 50 in a downward direction, inserting the sliding protrusion 53 into the sliding groove 21 (refer to FIG. 2) and then causing the dust collectors 40 and 50 to slide in the lateral direction, the dust collectors 40 and 50 may be coupled to the main body 10. The downward direction may indicate a direction intersecting the lateral direction. In this case, the sliding protrusion 53 may be elastically deformed to be inserted into the sliding groove 21. By inserting the sliding protrusion 53 into the sliding groove 21 and causing the dust collectors 40 and 50 to slide in the lateral direction, the dust collectors 40 and 50 may be coupled to the main body 10. A process of inserting the sliding protrusion 53 into the sliding groove 21 will be described later.
As shown in FIG. 12, by rotating the dust collectors 40 and 50, the dust collectors 40 and 50 may be coupled to the main body 10. By after aligning the button 100 with the button coupling portion 70 and then rotating the dust collectors 40 and 50 by using an end of the button 100 as a central axis, the dust collectors 40 and 50 may be coupled to the main body 10. Like FIG. 11, the sliding protrusion 53 may be inserted into the sliding groove 21, and a detailed description thereof will be given later.
As described above, according to the cleaner 1 of the disclosure, the dust collectors 40 and 50 may be coupled to the main body 10 by various methods and in various directions. Accordingly, the user may select a most convenient method according to his/her preference to couple the dust collectors 40 and 50 to the main body 10. By providing various coupling methods, various users' needs may be satisfied, and ease of use of the cleaner 1 may be improved.
FIGS. 13 and 14 illustrate a process of inserting a sliding protrusion into a sliding groove in the cleaner according to an embodiment of the disclosure.
Hereinafter, a process of inserting the sliding protrusion 53 into the sliding groove 21 in the cleaner 1 according to an embodiment of the disclosure will be described in detail.
The sliding protrusion 53 may be elastically deformable. The sliding protrusion 53 may be received in the protrusion housing 52. Because the sliding protrusion 53 is elastically deformed in the protrusion housing 52, a length of a portion of the sliding protrusion 53 by which the sliding protrusion 53 protrudes to the outside of the protrusion housing 52 may change.
In the following description, a first direction and a second direction may be different from the first direction and the second direction as described above.
The sliding rail 20 may extend in a first direction. A pair of the sliding rails 20 may be provided. A sliding groove 21 may be formed between the sliding rails 20. The sliding groove 21 may extend in the first direction.
The sliding protrusion 53 may slide in the first direction to be inserted into the sliding groove 21. The sliding protrusion 53 may slide without being elastically deformed to be inserted into the sliding groove 21.
The sliding protrusion 53 may be elastically deformed to move in a second direction intersecting the first direction. The second direction may indicate left and right directions in the drawings.
The sliding protrusion 53 may move in a third direction intersecting the first and second directions to be inserted into the sliding groove 21. The third direction may indicate up and down directions in the drawings.
Referring to FIG. 13, when the dust collectors 40 and 50 move in the downward direction, the sliding protrusion 53 may be elastically deformed to move in the second direction. The sliding rail 20 may include a first guide surface 20 a for guiding the sliding protrusion 53 to move in the second direction. The sliding protrusion 53 may include a second guide surface 53 a being in contact with the first guide surface 20 a and guided by the first guide surface 20 a. When the dust collectors 40 and 50 move in the third direction by the first guide surface 20 a and the second guide surface 53 a, the sliding protrusion 53 may move smoothly in the second direction.
Referring to FIG. 14, when the dust collectors 40 and 50 further move in the downward direction, the sliding protrusion 53 may move in a direction that is opposite to the second direction to return to its original position. The sliding protrusion 53 may include a stopper protrusion 53 b for preventing the sliding protrusion 53 from protruding more than a predetermined distance from the protrusion housing 52. The protrusion housing 52 may include a stopper 52 a for coming in contact with the stopper protrusion 53 b to restrict a movement of the sliding protrusion 53. By providing the stopper protrusion 53 b and the stopper 52 a, the sliding protrusion 53 may be prevented from protruding from the protrusion housing 52 more than a width of the sliding groove 21. Therefore, the sliding protrusion 53 being not inserted into the sliding groove 21 in the first direction may be prevented.
When the sliding protrusion 53 is inserted into the sliding groove 21, the sliding protrusion 53 may move in the first direction or in the opposite direction of the first direction. When the sliding protrusion 53 is inserted into the sliding groove 21, the sliding protrusion 53 may be restricted from moving in a direction that is opposite to the third direction. In other words, when the sliding protrusion 53 is inserted into the sliding groove 21, the movement of the sliding protrusion 53 in the upward direction may be restricted. This is because there is no guide surface to guide the sliding protrusion 53 when the sliding protrusion 53 moves in the upward direction.
FIG. 15 illustrates the main body and the dust container assembly separated from the main body in the cleaner according to an embodiment of the disclosure, and FIG. 16 illustrates the main body and the dust container assembly shown in FIG. 15 at another angle.
As described above, through the sliding protrusion 53 and the sliding groove 21, the dust collectors 40 and 50 may be coupled to the main body 10 by various methods and in various direction, and ease of use of the cleaner 1 may be improved.
According to an embodiment of the disclosure, the cleaner 1 may include a dust container fixer 200. Hereinafter, the dust container assemblies 40 and 50 may indicate the dust separator 40, and the dust container 50 coupled to the dust separator 40. The dust container assemblies 40 and 50 may include the dust separator 40 and the dust container 50.
The dust container fixer 200 may prevent the dust container assemblies 40 and 50 from falling down, which may occur when the dust container assemblies 40 and 50 are separated from the main body 10.
The dust container fixer 200 may include a first fixer 210 provided in the main body 10 and a second fixer 220 provided in the dust container 50. A detailed description of the dust container fixer 200 will be given later.
FIG. 17 illustrates an enlarged view of a portion A of FIG. 15, FIG. 18 illustrates an enlarged view of a portion B of FIG. 16, and FIG. 19 illustrates a coupling relationship between the dust container, the sliding protrusion, and an elastic member in the cleaner according to an embodiment of the disclosure.
A configuration of the dust container fixer 200 according to an embodiment of the disclosure will be described below with reference to FIGS. 17 to 19.
Hereinafter, the first direction may indicate a −z axis direction and the second direction may indicate a +y axis direction or a −y axis direction in the drawings.
Referring to FIG. 17, the first fixer 210 may be provided in the main body 10. The first fixer 210 may include a sliding groove 211 extending in the first direction, a latching protrusion 212 provided at one end of the sliding groove 211, and a sliding rail 213 forming the sliding groove 211.
The sliding groove 211 may extend in the first direction in which the extension pipes 32 and 33 extend. A pair of the sliding grooves 211 may be provided. A sliding protrusion 221, which will be described later, may be received in the sliding groove 211.
The latching protrusion 212 may be provided at one end of the sliding groove 211. The latching protrusion 212 may be provided at the end of the sliding groove 211 in the first direction. The latching protrusion 212 may protrude from the sliding groove 211 in the second direction intersecting the first direction.
The sliding rail 213 may be positioned in front of the sliding groove 211 as shown in the drawing. The sliding rail 213 may extend along the first direction. Like the sliding groove 211, a pair of sliding rails 213 may be provided. The sliding rail 213 may prevent the sliding protrusion 221, which will be described later, from being taken out of the sliding groove 211 by moving in the x-axis direction of the drawing.
Referring to FIGS. 18 and 19, the second fixer 220 may include the protrusion housing 52, the sliding protrusion 221 received in the protrusion housing 52, and an elastic member 230 for providing an elastic force to the sliding protrusion 221.
The sliding protrusion 221 may reciprocate in the second direction inside the protrusion housing 52. A pair of the sliding protrusions 221 may be provided, and may move in a direction in which the sliding protrusions 221 approach each other or in a direction in which the sliding protrusion 221 are spaced away from each other. The elastic member 230 may provide an elastic force to move the pair of sliding protrusions 221 in the direction in which the sliding protrusions 221 are spaced away from each other.
The protrusion housing 52 may include a first opening 56 and a second opening 57. The sliding protrusion 221 may be inserted into the protrusion housing 52 through the first opening 56. A size of the sliding protrusion 221 may be larger than that of the first opening 56. Accordingly, the sliding protrusion 221 may be elastically deformed when the sliding protrusion 221 is inserted into the protrusion housing 52 through the first opening 56.
When the sliding protrusion 221 is inserted into the protrusion housing 52, a stopper 224 of the sliding protrusion 221 may be taken out through the second opening 57 of the protrusion housing 52. The stopper 224 may be movable in the second opening 57. A movement distance of the sliding protrusion 221 inside the protrusion housing 52 may be restricted by the stopper 224. Due to the stopper 224, the sliding protrusion 221 may not be taken out to the outside of the protrusion housing 52 through the first opening 56.
The sliding protrusion 221 may include an inclined surface. More specifically, the sliding protrusion 221 may include a first guide surface 222 inclined with respect to the first direction, and a second guide surface 223 inclined with respect to the third direction. In this case, the first direction indicates the −z axis direction in the drawing, and the third direction indicates a −x axis direction in the drawing.
Because the sliding protrusion 221 includes the first guide surface 222, the sliding protrusion 221 may pass through the latching protrusion 212 in the first direction.
Because the sliding protrusion 221 includes the second guide surface 223, the sliding protrusion 221 may be inserted into the sliding groove 211 in the third direction. In other words, because the sliding protrusion 221 includes the second guide surface 223, the sliding protrusion 221 may pass through the sliding rail 213 in the −x axis direction.
FIG. 20 illustrates a side view of the cleaner according to an embodiment of the disclosure, and FIG. 21 illustrates a side view of the cleaner according to an embodiment of the disclosure, showing a process of separating the dust container from the main body.
Referring to FIGS. 20 and 21, in the cleaner 1 according to an embodiment of the disclosure, when the dust container assemblies 40 and 50 are separated from the main body 10, the dust container assemblies 40 and 50 may not be immediately separated from the main body 10 by the dust container fixer 200.
Referring to FIG. 21, the dust container assemblies 40 and 50 may not be immediately separated from the main body 10 even when a user presses the button 100 to release the dust container assemblies 40 and 50 from the main body 10. More specifically, the dust container assemblies 40 and 50 may be prevented from moving by their own weights in the −z axis direction due to the sliding protrusion 221 caught by the latching protrusion 212. The user may completely separate the dust container assemblies 40 and 50 from the main body 10 by applying a greater force than the weights of the dust container assemblies 40 and 50 in the −z axis direction.
FIG. 22 is a cross-sectional view taken along line A-A′ of FIG. 20, illustrating a state of a coupling device when the dust container is coupled to the main body, FIG. 23 is a cross-sectional view taken along the line A-A′ of FIG. 20, illustrating a state in which the sliding protrusion is caught by the latching protrusion when the dust container is released from the main body, and FIG. 24 is a cross-sectional view taken along line A-A′ of FIG. 20, illustrating a process in which the sliding protrusion passes through the latching protrusion.
A process in which the sliding protrusion 221 according to an embodiment of the disclosure passes through the latching protrusion 212 will be described in detail below with reference to FIGS. 22 to 24.
Referring to FIG. 22, when the dust container assemblies 40 and 50 are coupled to the main body 10, the sliding protrusion 221 may be received in the sliding groove 211. The sliding protrusion 221 may be spaced apart from the latching protrusion 212 so as not to be in contact with the latching protrusion 212. The sliding protrusion 221 may be spaced by a predetermined distance in the +z axis direction from the latching protrusion 212.
The elastic member 230 may provide the elastic force to the pair of sliding protrusions 221 such that the sliding protrusions 221 are spaced away from each other. A distance between the pair of sliding protrusions 221 may become increased. The sliding protrusion 221 may be in contact with a side surface of the sliding groove 211.
Referring to FIG. 23, even when the user presses the button 100 to release the dust container assemblies 40 and 50 from the main body 10, the dust container assemblies 40 and 50 may be not separated from the main body 10 by the sliding protrusion 221 caught by the latching protrusion 212.
The sliding protrusion 221 may be in contact with the latching protrusion 212. More specifically, the first guide surface 222 of the sliding protrusion 221 may be in contact with a third guide surface 212 a of the latching protrusion 212. When the first guide surface 222 slides along the third guide surface 212 a by the weight of the dust container 50, each of the pair of sliding protrusions 221 may move in the +y axis direction or the −y axis direction. Accordingly, the distance between the pair of sliding protrusions 221 may be shorter than that shown in FIG. 22.
As shown in FIG. 24, when the user applies a greater force than the weight of the dust container assemblies 40 and 50 in the −z axis direction to separate the dust container assemblies 40 and 50 from the main body 10, the sliding protrusion 221 may pass through the latching protrusion 212. By the force applied by the user, the pair of sliding protrusion 221 may move in the +y axis or the −y axis direction despite the elastic force of the elastic member 230. The distance between the pair of sliding protrusions 221 may be reduced.
A side surface of the sliding protrusion 221 may be in contact with the latching protrusion 212. The sliding protrusion 221 may slide while being in contact with the latching protrusion 212. When the sliding protrusion 221 passes through the latching protrusion 212, the dust container assemblies 40 and 50 may be completely separated from the main body 10.
As described above, the cleaner 1 according to the disclosure may include the dust container fixer 200. The dust container fixer 200 may prevent the dust container assemblies 40 and 50 from immediately falling to a floor even when the user presses the button 100 accidentally. The dust container assemblies 40 and 50 may be first maintained in a state of being coupled to the main body 10 by the dust container fixer 200, and may be completely detached from the main body 10 when the user applies a predetermined force to the dust container assemblies 40 and 50 to separate the dust container assemblies 40 and 50 from the main body 10. Thereby, the dust container assemblies 40 and 50 in the cleaner 1 according to the disclosure may be prevented from falling down contrary to the user's intention. Therefore, a hassle to again perform cleaning due to dust scattered when the dust container assemblies 40 and 50 fall down may be reduced.
FIGS. 25 and 26 illustrate various methods of coupling the dust container assembly to the main body in the cleaner according to an embodiment of the disclosure.
According to the disclosure, the dust container 50 may be coupled to the main body 10 by various methods.
As shown in FIG. 26, by aligning the center of the dust container assemblies 40 and 50 with the center of the filter housing 15 and making the dust container assemblies 40 and 50 slide in the +z axis direction, the dust container assemblies 40 and 50 may be coupled to the main body 10. When the dust container assemblies 40 and 50 are coupled to the main body 10 in this method, the sliding protrusion 221 may not move in the y axis direction. The sliding protrusion 221 may be inserted into the sliding groove 211 by sliding in the +z axis direction along the sliding groove 211.
As shown in FIG. 26, the sliding protrusion 221 may be inserted into the sliding groove 211 by positioning the button 100 to correspond to the button coupling portion provided in the main body 10 and rotating the dust container assemblies 40 and 50. A process in which the sliding protrusion 221 passes through the sliding rail 213 and is inserted into the sliding groove 211 will be described later.
According to the cleaner 1 of the disclosure, the dust container assemblies 40 and 50 may be coupled to the main body 10 by various methods and in various directions. Accordingly, the user may select a most convenient method according to his/her preference to couple the dust container assemblies 40 and 50 to the main body 10. By providing various coupling methods, various users' needs may be satisfied, and ease of use of the cleaner 1 may be improved.
FIGS. 27 and 28 are views illustrating a process of inserting the sliding protrusion into the sliding groove in the cleaner according to an embodiment of the disclosure.
Hereinafter, a process in which the sliding protrusion 221 passes through the sliding rail 213 and is inserted into the sliding groove 211 in the cleaner 1 according to an embodiment of the disclosure will be described in detail.
As described above, the sliding protrusion 221 may move in the +y axis or −y axis direction when a greater force than the elastic force of the elastic member 230 is applied. When the pair of sliding protrusions 221 move in a direction in which the sliding protrusions 221 approach each other, the pair of sliding protrusions 221 may pass through the sliding rail 213 in the −x axis direction. The −x axis direction is referred to as the third direction.
Referring to FIG. 27, the sliding protrusion 221 may include the second guide surface 223 inclined with respect to the third direction. The sliding protrusion 221 may include the second guide surface 223 inclined with respect to the third direction in addition to the first guide surface 222 inclined with respect to the first direction.
When the sliding protrusion 221 moves in the third direction, the second guide surface 223 may come into contact with the sliding rail 213. The sliding rail 213 may include a fourth guide surface 213 a to guide the sliding protrusion 221 to pass through the sliding rail 213 in the third direction.
The second guide surface 223 of the sliding protrusion 221 may be guided by the fourth guide surface 213 a of the sliding rail 213. Thereby, the sliding protrusion 221 may move in the −x axis direction, and simultaneously move in the +y axis direction or the −y axis direction. Therefore, as shown in FIG. 14, the distance between the pair of sliding protrusions 221 may be reduced when the sliding protrusions 221 move in the −x axis direction.
Referring to FIG. 28, the sliding protrusion 221 that has passed through the sliding rail 213 may be inserted into the sliding groove 211. After passing through the sliding rail 213, the pair of sliding protrusions 121 may move to be spaced away from each other by the elastic force of the elastic member 230.
When the sliding protrusion 221 is inserted into the sliding groove 211, the dust container assemblies 40 and 50 may be prevented from being separated from the main body 10 in the +x axis direction. The reason is because the sliding protrusion 221 is incapable of being taken out of the sliding groove 211 in the +x axis direction. A lower surface of the sliding rail 213 in the drawing may not be inclined. An upper surface of the sliding protrusion 221 in the drawing may not be inclined. Accordingly, the upper surface of the sliding protrusion 221 and the lower surface of the sliding rail 213 may form a substantially horizontal contact surface. In this case, even when the user applies a force to the dust container assemblies 40 and 50 in the +x axis direction, the sliding protrusion 221 may not move in the +y axis direction or the −y axis direction, and the dust container assemblies 40 and 50 may not be separated from the main body 10. Thereby, the dust container assemblies 40 and 50 may be prevented from being separated from the main body 10 contrary to a user's intention when the user does not press the button 100.
As is apparent from the above, according to a concept of the disclosure, there may be provided a cleaner capable of separating a dust separator from a main body and separating a dust container from the dust separator by using a button.
According to another concept of the disclosure, there may be provided a cleaner capable of preventing a dust container from being separated from a dust separator when a dust collector is separated from a main body.
According to another concept of the disclosure, there may be provided a cleaner capable of coupling a dust collector to a main body in various directions.
According to another concept of the disclosure, there may be provided a cleaner capable of preventing a dust container from falling down due to a user's carelessness when the dust container is separated.
According to another concept of the disclosure, there may be provided a cleaner including a dust container fixer capable of preventing a dust container from falling down when the dust container is decoupled from a main body.
Although the present disclosure has been described with various embodiments, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
